Water Resistance Therapy For Voice Training: Research Findings And Practical Demonstrations
Thursday 7th October 2021, 5:00 PM - 7:00 PM (London Time)
Several types of SOVTE have been used and described in both voice rehabilitation and voice training.
The water resistance therapy (WRT) method (a type of SOVTE) consists of phonating different phonatory tasks into a glass tube, keeping the distal end of the tube submerged in water. Research on WRT has suggested the presence of a massage-like effect on vocal folds and vocal tract tissues, and changes in aerodynamic measures, electroglottographic (EGG) contact quotient (CQ), and vocal tract configuration.
These effects are assumed to contribute to vocal economy. Poral modulation during water bubbling has been established at a frequency of 12-40 Hz. The magnitude of variation of Poral during tube phonation in water has also been examined. Several practical variables affect water bubbling during WRT and they should be controlled when using this exercise for voice training.
The present course was designed to provide information about the variables that need to be controlled during WRT based on research findings. Practical demonstrations on how to properly performs WRT are also considered.

Thinking Outside the Voice Box: Adolescent Female Voice Change
Dr Bridget Sweet-Manternach
Join Dr Bridget Sweet for this 2 hour session as she unpacks this fascinating topic. The purpose of this course is to bring attention to adolescents who experience an estrogen-dominant voice change and to encourage new and holistic ways of thinking about [assigned at birth] female voices. While considering physical changes during adolescence, we will unpack basic vocal anatomy and physiology and then discuss what happens to the vocal mechanism during voice change for females vs. [assigned at birth] males.
